Carboxymethylcellulose (CMC) yog ntau yam polymer siv nyob rau hauv ntau yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev lag luam khoom noj khoom haus uas nws yog xam tau tias yog ib qho khoom noj-qib additive.Cov tshuaj no yog muab los ntawm cellulose, ib tug natural polymer pom nyob rau hauv cov nroj tsuag cell phab ntsa.Los ntawm kev hloov kho tshuaj lom neeg, carboxymethyl cellulose yog tsim, muab nws cov khoom tshwj xeeb thiab ua rau nws muaj txiaj ntsig rau ntau daim ntawv thov.
Qauv thiab ntau lawm:
Cellulose yog ib qho nyuaj carbohydrate thiab yog ib qho tseem ceeb ntawm CMC.Cellulose feem ntau yog muab los ntawm cov ntoo pulp lossis paj rwb fibers.Cov txheej txheem tsim khoom suav nrog kev kho cellulose nrog sodium hydroxide los tsim cov alkali cellulose.Tom qab ntawd, pawg carboxymethyl tau nkag mus rau hauv cov pob txha cellulose siv chloroacetic acid.Qhov kev hloov pauv ntawm cov txiaj ntsig carboxymethyl cellulose tuaj yeem sib txawv thiab hais txog cov pawg carboxymethyl ntxiv rau ib chav tsev piam thaj hauv cov saw cellulose.
yam ntxwv:
CMC muaj ob peb key cov khoom uas ua rau nws muaj ntau yam kev siv:
Dej solubility: CMC yog dej-soluble thiab tsim cov pob tshab thiab viscous tov hauv dej.Cov cuab yeej no yog qhov tseem ceeb rau nws siv ntau hom kua formulations.
Thickeners: Raws li cov thickener, CMC feem ntau yog siv los ua kom cov viscosity ntawm cov khoom noj.Cov cuab yeej no muaj txiaj ntsig tshwj xeeb rau kev txhim kho kev ntxhib los mos thiab lub qhov ncauj ntawm cov kua ntses, hnav khaub ncaws thiab lwm yam khoom noj ua kua.
Stabilizer: CMC ua tus stabilizer hauv ntau cov khoom noj, tiv thaiv cov khoom xyaw los ntawm kev sib cais los yog nyob rau lub sijhawm khaws cia.Qhov no yog ib qho tseem ceeb rau kev tswj qhov sib xws ntawm daim ntawv qhia.
Kev ua yeeb yaj kiab: CMC muaj peev xwm ua yeeb yaj kiab thiab tuaj yeem siv los ua cov txheej txheem rau cov khoom qab zib xws li khoom qab zib thiab chocolates.Cov zaj duab xis tsim pab tswj kom zoo thiab zoo li ntawm cov khoom.
Suspending agent: Hauv cov dej haus thiab qee yam khoom noj, CMC yog siv los ua tus neeg sawv cev ncua kev tiv thaiv kom tsis txhob muaj teeb meem.Qhov no ua kom muaj kev faib tawm zoo ib yam ntawm cov khoom xyaw.
Binders: CMC ua raws li cov ntaub ntawv hauv cov khoom noj, pab khi cov khoom xyaw ua ke thiab txhim kho tag nrho cov qauv ntawm cov khoom kawg.
Non-toxic thiab inert: Khoom noj khoom haus-qib CMC suav hais tias muaj kev nyab xeeb rau kev noj vim nws tsis muaj tshuaj lom thiab tsis muaj zog.Nws tsis muab qhov tsw lossis xim rau cov khoom noj uas nws siv.
Daim ntawv thov nyob rau hauv cov zaub mov industry:
Carboxymethylcellulose yog siv dav hauv kev lag luam khoom noj khoom haus thiab pab txhim kho qhov zoo thiab ruaj khov ntawm ntau yam khoom.Qee cov ntawv thov tseem ceeb suav nrog:
Cov Khoom Ci: CMC yog siv rau hauv cov khoom ci xws li khob cij thiab khoom qab zib los txhim kho kev ntxhib los mos, khaws noo noo thiab txee lub neej.
Cov khoom siv mis nyuj: Hauv cov khoom siv mis nyuj xws li ice cream thiab yogurt, CMC ua lub stabilizer thiab pab tiv thaiv cov dej khov los ntawm kev tsim.
Sauces thiab hnav khaub ncaws: CMC yog siv los ua kom tuab thiab ruaj khov cov kua ntses, hnav khaub ncaws thiab khoom noj khoom haus, txhim kho lawv cov khoom zoo.
Dej haus: Siv hauv cov dej haus los tiv thaiv sedimentation thiab txhim kho particle suspension, kom ntseeg tau cov khoom sib xws.
Confectionery: CMC yog siv nyob rau hauv kev lag luam confectionery rau lub tsho tiv no cov khoom qab zib thiab chocolates, muab ib tug tiv thaiv txheej thiab txhim kho tsos.
Glazes thiab Frostings: CMC pab txhim kho kev ntxhib los mos thiab ruaj khov ntawm glazes thiab frostings siv hauv pastries thiab khoom qab zib.
Cov nqaij ua tiav: CMC tau ntxiv rau cov nqaij ua tiav los txhim kho cov dej tuav, kev ntxhib los mos thiab khikhoom.
Regulatory status thiab kev nyab xeeb:
Khoom noj khoom haus qib CMC yog tswj los ntawm cov koom haum saib xyuas zaub mov thoob ntiaj teb.Nws feem ntau lees paub tias muaj kev nyab xeeb (GRAS) los ntawm US Food and Drug Administration (FDA) thiab tau pom zoo siv rau ntau yam khoom noj.The Joint FAO/WHO Pawg Kws Tshaj Lij rau Cov Khoom Noj Ntxiv (JECFA) thiab lwm lub koom haum tswj hwm kuj tau soj ntsuam thiab txiav txim siab txog kev nyab xeeb ntawm CMC rau kev siv zaub mov.
Carboxymethylcellulose (CMC) yog ib qho tseem ceeb ntawm cov zaub mov qib additive nrog ntau yam kev siv hauv kev lag luam khoom noj.Nws cov khoom tshwj xeeb, xws li dej solubility, thickening peev xwm thiab zaj duab xis-tsim muaj peev xwm, ua rau nws muaj txiaj ntsig muaj txiaj ntsig hauv ntau hom khoom noj.Kev tswj hwm kev pom zoo thiab kev ntsuas kev nyab xeeb ntxiv hais txog nws qhov tsim nyog rau kev lag luam zaub mov thiab dej haus.
